(LAS VEGAS CBS KXNT) The three-year I-15 South project is approaching completion as newly-configured access lanes to Russell Road open on Tuesday morning.

The map nearby shows the ramps from the 215 Bruce Woodbury Beltway at I-15. From the eastbound and westbound directions, commuters will no longer enter northbound I-15 in order to get to Russell Road. Instead, the Russell Road access lanes will lead traffic directly from both directions of 215 along side the freeway to the Russell exit.

The Russell exit lanes will also carry traffic to the Tropicana and Frank Sinatra exits. The current Frank Sinatra/Tropicana exit from northbound I-15 will be closed with a concrete barrier on Monday night.

KXNT took a ride with Craig Bells of Las Vegas Paving Corporation, who has been supervising the $246 million project stretching from Tropicana to Blue Diamond. The project is designed to make I-15 traffic move more smoothly, Bells told KXNT, with fewer back-ups and accidents that result from last minute lane changes.

The speed limit on the access roads is 45 miles per hour, although Bells says he has yet to see drivers observe it. Bells believes the highway patrol has been allowing a grace period while the construction is completed and drivers become accustomed to the new ramps. That may change, he told KXNT.

The I-15 South project will be complete late this summer after the widening of the Warm Springs bridge.
